On keyring-less headless Linux (VPS, containers, no dbus session),
'gh auth login --with-token' can block indefinitely waiting on a
secret-service keyring -- even with --insecure-storage, with no output.
Hit live on a headless x86_64 VPS (gh 2.97.0): the documented device
flow succeeded up to the token, then --with-token hung twice.
- Add a timeout guard to the device-flow polling loop so the hang is
detected instead of silently stalling the login.
- Document the proven fallback: write ~/.config/gh/hosts.yml directly
(chmod 600) and run 'gh auth setup-git' -- both read the file store
without touching the keyring.
